The DC Metropolitan Area Drug Study (DCMADS) was

conducted in 1991, and included special analyses of homeless and

transient populations and of women delivering live births in the DC

hospitals. DCMADS was undertaken to assess the full extent of the

drug problem in one metropolitan area. The study was comprised of 16

separate studies that focused on different sub-groups, many of which

are typically not included or are underrepresented in household

surveys. The Homeless and Transient Population

study examines the prevalence of illicit drug, alcohol, and tobacco

use among members of the homeless and transient population aged 12 and

older in the Washington, DC, Metropolitan Statistical Area (DC

MSA). The sample frame included respondents from shelters, soup

kitchens and food banks, major cluster encampments, and literally

homeless people. Data from the questionnaires include history of

homelessness, living arrangements and population movement, tobacco,

drug, and alcohol use, consequences of use, treatment history, illegal

behavior and arrest, emergency room treatment and hospital stays,

physical and mental health, pregnancy, insurance, employment and

finances, and demographics. Drug specific data include age at first

use, route of administration, needle use, withdrawal symptoms,

polysubstance use, and perceived risk.This study has 1 Data Set.

This series measures the prevalence and correlates of drug use in the United States. The surveys are designed to provide quarterly, as well as annual, estimates. Information is provided on the use of illicit drugs, alcohol, tobacco, and nonmedical use of prescription drugs among members of United States households aged 12 and older. Questions include age at first use, as well as lifetime, annual, and past-month usage for the following drug classes: cannabis, cocaine, hallucinogens, heroin, alcohol, tobacco, and nonmedical use of prescription drugs, including psychotherapeutics. Respondents were also asked about problems resulting from their use of drugs, alcohol, and tobacco, their perceptions of the risks involved, and personal and family income sources and amounts. Half of the respondents were asked questions regarding substance use by close friends. Demographic data include gender, race, age, ethnicity, educational level, job status, income level, veteran status, household composition, and population density. Youth respondents were also asked about time spent on homework and leisure activities.This study has 1 Data Set.

The National Survey on Drug Use and Health (NSDUH) series

(formerly titled National Household Survey on Drug Abuse) measures the

prevalence and correlates of drug use in the United States. The

surveys are designed to provide quarterly, as well as annual,

estimates. Information is provided on the use of illicit drugs,

alcohol, and tobacco among members of United States households aged 12

and older. Questions included age at first use as well as lifetime,

annual, and past-month usage for the following drug classes:

marijuana, cocaine (and crack), hallucinogens, heroin, inhalants,

alcohol, tobacco, and nonmedical use of prescription drugs, including

pain relievers, tranquilizers, stimulants, and sedatives. The survey

covered substance abuse treatment history and perceived need for

treatment, and included questions from the Diagnostic and Statistical

Manual (DSM) of Mental Disorders that allow diagnostic criteria to be

applied. The survey included questions concerning treatment for both

substance abuse and mental health related disorders. Respondents were

also asked about personal and family income sources and amounts,

health care access and coverage, illegal activities and arrest record,

problems resulting from the use of drugs, and needle-sharing.

Questions introduced in previous administrations were retained in the

2003 survey, including questions asked only of respondents aged 12 to

17. These "youth experiences" items covered a variety of topics, such

as neighborhood environment, illegal activities, gang involvement,

drug use by friends, social support, extracurricular activities,

exposure to substance abuse prevention and education programs, and

perceived adult attitudes toward drug use and activities such as

school work. Several measures focused on prevention related themes in

this section. Also retained were questions on mental health and access

to care, perceived risk of using drugs, perceived availability of

drugs, driving and personal behavior, and cigar smoking. Questions on

the tobacco brand used most often were introduced with the 1999 survey

and retained through the 2003 survey. Background information includes

gender, race, age, ethnicity, marital status, educational level, job

status, veteran status, and current household composition. A number of additional questions were added in 2003, including questions on prior marijuana and cigarette use, additional questions on drug treatment, adult mental health services, and social environment.This study has 1 Data Set.

activities, problems resulting from the use of drugs, personal and

family income sources and amounts, need for treatment for drug or

alcohol use, criminal record, and needle-sharing. Questions on mental

health and access to care, which were introduced in the 1994-B

questionnaire (see NATIONAL HOUSEHOLD SURVEY ON DRUG ABUSE, 1994), were retained in this administration of the survey. In

1996, the section on risk/availability of drugs was reintroduced, and

sections on driving behavior and personal behavior were

added. Demographic data include gender, race, age, ethnicity, marital

status, educational level, job status, income level, veteran status,

and current household composition.This study has 1 Data Set.

The National Survey on Drug Use and Health (NSDUH) series (formerly titled National Household Survey on Drug Abuse) primarily measures the prevalence and

correlates of drug use in the United States. The surveys are designed to provide quarterly, as well as annual estimates. Information is provided on the use

of illicit drugs, alcohol, and tobacco among members of United States households aged 12 and older. Questions included age at first use as well as

lifetime, annual, and past-month usage for the following drug classes: marijuana, cocaine (and crack), hallucinogens, heroin, inhalants, alcohol, tobacco,

and nonmedical use of prescription drugs, including pain relievers, tranquilizers, stimulants, and sedatives. The survey covered substance abuse treatment

history and perceived need for treatment, and included questions from the Diagnostic and Statistical Manual (DSM) of Mental Disorders that allow diagnostic

criteria to be applied. The survey included questions concerning treatment for both substance abuse and mental health-related disorders. Respondents were

also asked about personal and family income sources and amounts, health care access and coverage, illegal activities and arrest record, problems resulting

from the use of drugs, and needle-sharing. Questions introduced in previous administrations were retained in the 2015 survey, including questions asked

only of respondents aged 12 to 17. These "youth experiences" items covered a variety of topics, such as neighborhood environment, illegal activities, drug

use by friends, social support, extracurricular activities, exposure to substance abuse prevention and education programs, and perceived adult attitudes

toward drug use and activities such as school work. Several measures focused on prevention-related themes in this section. Also retained were questions on

mental health and access to care, perceived risk of using drugs, perceived availability of drugs, driving and personal behavior, and cigar smoking.

Questions on the tobacco brand used most often were introduced with the 1999 survey. For the 2008 survey, adult mental health questions were added to

measure symptoms of psychological distress in the worst period of distress that a person experienced in the past 30 days and suicidal ideation. In 2008, a

split-sample design also was included to administer separate sets of questions (WHODAS vs. SDS) to assess impairment due to mental health problems.

Beginning with the 2009 NSDUH, however, all of the adults in the sample received only the WHODAS questions. Background information includes gender, race,

age, ethnicity, marital status, educational level, job status, veteran status, and current household composition.This study has 1 Data Set.
